Two thoughts here...
1 - While nail #1 looks relatively close to the boundary line, I'd say that it's far enough in that it's worth plugging/patching from the inside. #2 definitely looks repairable. I'd think that if a proper plug and patch was done from the inside of the tire, you'd be okay to drive on those. If it were me, I'd take it to a Discount Tire and ask them to repair the tire, especially since it looks like there's a TON of tread on that. I'd guess at least 10/32"
2 - Judging by the tread pattern on that tire, I'm guessing it's a Uniroyal Tiger Paw or Tiger Paw Touring. I don't know the size that your car takes, but I do know that you can buy a new one of those for under $100 at WalMart in 215/55R17 size - 94V rating, 55,000 mile warranty. If a plug won't work, at least since the ones on there are nearly new, you could just replace the 1 and still be in decent shape.
.... If it were me, though, I'd just repair it and go.
